ConfiguredGraphFactory and Authentication not working


Vinayak Bali
 

Hi All,

Followed the following blogs for configuring authentication and ConfiguredGraphFactory respectively.



Still, both of them are not working. Sharing the property files.

# JanusGraph configuration sample: Cassandra over a socket

# The primary persistence provider used by JanusGraph.  This is required.
# It should be set one of JanusGraph's built-in shorthand names for its
# standard storage backends (shorthands: berkeleyje, cql, cassandrathrift,
# cassandra, astyanax, embeddedcassandra, hbase, inmemory) or to the full
# package and classname of a custom/third-party StoreManager
# implementation.
#
# Default:    (no default value)
# Data Type:  String
# Mutability: LOCAL
storage.backend=cql

# The configuration management graph reserved for use with JanusGraphManager

Please add a key named "ConfigurationManagementGraph" to the "graphs" property in your YAML file and restart the server to be able to use the functionality of the ConfigurationManagementGraph class.

Request you to check and help me to solve the issue.

Thanks & Regards,
